Yep, that was in the back of my mind.  Probably needs more abstraction
to make that cleaner.

sure, I can break it up.

many of them likely fail, too, some of the acl & attr tests have some
assumptions about xfs limits.

Ok.  I'd even thought that maybe by default, w/o options, it should just
run as whatever $TEST_DEV is formatted to (though that's trickier for
nfs I guess)

I think this is because even for udf etc, it still expects $TEST_DIR to
be xfs, so swizzles around test & scratch. yeah, I agree that's messy.

yeah, after I ran it a bit more I think I tend to agree....

I'll work on breaking this up a bit and tidying up some of the loose
ends, since the basic approach seems sane to more than one person now  :)
